DIY: Sew your own smartphone case

DIY: Smartphone-Hülle selbst nähen

Self-sewn smartphone cases are a wonderful gift that can be customized to suit your own personal taste. However, our smartphone case comes with an extra special feature: it is lined with a soft microfiber fabric that cleans the phone's display of dust and fingerprints while you use it – practically in passing.

Sewing a smartphone case: Would you have thought it was this easy?

If you are worried that your smartphone might react poorly to the magnetic snap, you can replace it at any time with a Velcro fastener or a Kam Snap.

For our smartphone case you will need:

  • Fabric for the outside, perhaps a bit more for an extra pocket, e.g., for headphones
  • Microfiber for the inside (a regular household microfiber cloth works best here!)
  • Fleece for reinforcement
  • Velcro, or a magnetic snap or press stud if necessary
  • Optional: lace, ribbon, yo-yos
  • Our free sewing pattern: Smartphone case
What you need for our smartphone case: fabric for the outside, microfiber for the inside.

If you like, you can additionally reinforce the outer fabric with fleece.

Preparing the closure flap: reinforced with fleece, sewn with a narrow seam allowance, leave an opening for turning.

The corners of the closure flap are now trimmed.

The corners of the closure flap are now trimmed. This makes it easier to shape them later. Sew the edges together, iron. Now mark the center of the flap and the center of the back piece.

Smartphone case: cut the headphone pocket on the fold.

If you like, you can add an extra pocket for headphones or business cards.

I marked the desired height of the pocket on the pattern and cut the pocket on the fold.

Then I reinforced the edge with bias tape and decorated it with lace.

Inner parts right sides together, outer parts also right sides together.
Leave an opening for turning in the inner part. Sew all the way around. Trim the seam allowances.

The seam allowance of the lining is folded inwards and pinned in place.
Smartphone case: attach magnetic closure.
Attach the magnetic closure. I use vinyl thread for this because it is inconspicuous and very tear-resistant.
Smartphone case: done!
I also decorated the flap with a small mirror. Done!

Have fun sewing it yourself and Happy Simple Sewing

Sabine

I come from Siegen-Wittgenstein, where I spent my childhood breaking in cows, jumping off haystacks and scraping a D- in needlework class.

Today, being creative feels like indescribable happiness to me – and it grows even more when I can share it with others. Since 2016 I have been celebrating my passion for sewing on this blog, and I love that sewing connects so many people.
